Crops: Spring Transplant, Spring, Fall Transplant, Fall
Growing Season: Long
Growing Conditions: Cold, Cool, Warm, Hot. Collards are such a long season crop, they are usually direct sown 20 to 30" apart in mid spring. Wait until the cold weather has passed, so there is no chance of them being vernalized (which could cause them to bolt). Though Collards are most tender and better flavored when grown in cool weather, they do tolerate heat.
Outdoor Growing Temp: 40°F - 80°F
Min Outdoor Soil Temp: 45°F. Collards are pretty hardy and can go into the ground when it is still fairly cold. However they will germinate and grow faster in warmer soil.
Start Indoors: Yes
Start Outdoors: Yes
Light: Sun: min. 6 hours daily (Cold, Cool, Warm, Hot). Collards will be most productive in full sun, though they will tolerate partial shade.

Soil Preparation
Soil pH: 6.0-7.5, Ideal 6.5-7.0. Collards are tolerant of poor soil but the most palatable leaves are produced by rapid uninterrupted growth. For this the soil must be rich and moisture retentive. It is important that the soil is well drained when growing collards as a winter crop. If the soil is too wet the roots may rot.
Soil Preparation:
Compost (Nitrogen), 2”, in top 6” of soil, 1 time: Collards like organic matter, so amend the soil by digging in 2˝ of compost or aged manure.
Standard Mix, 5 pounds per 100 sq. ft., in top 6" of soil, 1 time: Standard Mix will supply any additional nutrients required and should be incorporated along with the compost.
This mix consists of:
- 4 parts cottonseed meal (this is high in nitrogen and relatively inexpensive)
- 2 parts colloidal phosphate or bone meal (for phosphorus)
- 2 parts wood ash or 3 parts greensand or granite dust (for potassium)
- 1 part dolomitic limestone (to balance pH and add calcium and magnesium)
- 1 part kelp meal (for trace elements)
Start Indoors
Soil temp for germination: 40°F to 95°F, optimal 65°F to 80°F, optimal 75°F
Total weeks to grow transplant: 10 to 11 (Spring/Summer), 10 to 13 (Fall/Winter)
Germinate:
6-8 weeks before last frost date: Collards are often started indoors for planting out in early spring and harvesting in early summer. Where insects or other pests are a problem Collards should be planted indoors. Collards don’t mind transplanting and can be started in flats, as well as cell packs and soil blocks.
Germinate:
14-16 weeks before first frost date: Where insects or other pests are a problem Collards should be planted indoors. Collards don’t mind transplanting and can be started in flats, as well as cell packs and soil blocks.
Transplant Outdoors
8-10 weeks before first frost date: The seedlings should go outside when they have 4 or 5 true leaves and are about 5˝ high. Using floating row covers and cloches while plants are young will deter pests and also help to stabilize temperature and conserve moisture.
Cold, Cool, Warm, Hot: Collards are such a long season crop, they are usually direct sown 20 to 30" apart in mid spring. Wait until the cold weather has passed, so there is no chance of them being vernalized (which could cause them to bolt). Though Collards are most tender and better flavored when grown in cool weather, they do tolerate heat.
When outdoor temp: 40°F to 80°F, optimal temp 60°F to 65°F.
When min soil temp: 45°F. Collards are pretty hardy and can go into the ground when it is still fairly cold. However they will germinate and grow faster in warmer soil.
Spacing: 12-18", 1 plants per sq ft. Collards are such a long season crop, they are usually direct sown 2 to 3" apart. As the planting fills in, it is gradually harvest thinned, first to 6", then to 12" and then (if the plants get big enough) to a final spacing of 15 to 18".
Start Outdoors

Spring Crop:
2-8 weeks before last frost date: Where insects or other pests are a problem Collards should be started indoors. If pests are not a problem sow directly.
Collard seeds germinate fast and grow quickly, so they are easily direct sown.
1. Plant the seeds ¼˝ to ½˝ deep and 2˝ apart.
You can save time and space by planting your autumn Collards as an intercrop into an existing summer crop. It will gradually take over the space as the weather gets cooler.
Fall Crop:
8-12 weeks before first frost date: Where insects or other pests are a problem Collards should be started indoors. If pests are not a problem sow directly.
Collard seeds germinate fast and grow quickly, so they are easily direct sown.
1. Plant the seeds ¼˝ to ½˝ deep and 2˝ apart.
You can save time and space by planting your autumn Collards as an intercrop into an existing summer crop. It will gradually take over the space as the weather gets cooler.
Water Needs: Moderate. Collards must have plenty of water for maximum productivity and best quality.
Fertilizer Needs: Heavy. Low nitrogen. Moderate potassium. Moderate phosphorous. Collards have similar nutritional requirements as kale, in that it needs a significant amount of phosphorus and potassium, but not a lot of nitrogen. It will flower early with too much nitrogen.
Weeding, after transplanting: after transplanting, every 2 weeks. Collards are is pretty independent once established, so you only really need worry about weeds while young.
Side Dressing, after transplanting: Compost tea, 5 gallon(s) per 100 sq. ft., after transplanting, every 4 weeks. Feed the plants with compost tea or liquid kelp, starting as soon as they have recovered from transplanting and every month thereafter. This is especially important if you are harvesting regularly.
Watering, after sowing: Water, 0.5 gallons per plant, after sowing, 1 time a week If the temperature is warm and your soil dries faster, then do this twice a week. Watering also depends on your local weather; don't water if it's raining, or water more frequently if it's dry. Just be sure to keep soil moist for the best crop. The best way to know how much moisture is in your soil is to feel 2" below the soil line. If it's dry, water.
Thinning, after planting: inches apart, after planting, every 3 weeks. As Collards fill in; they are gradually thinned/harvest, first to 6˝, then to 12˝ and then (if the plants get big enough) to a final spacing of 15 to 18˝. Or you can take leaves from the bottom of the plants and leave the growing heart alone.
Side Dressing, to cool soil: Mulch, 2 inches, to cool soil, 1 time. If necessary, use a mulch in summer to suppress weeds, keep the soil cool and conserve soil moisture.
Harvesting
Look for richly thick, green leaves. Collards can be harvested repeatedly, often sending out new leaves for 6 months or more. If you consistently harvest you will extend the growing cycle.
When and How:
Whole Fruit: 1-120 days after maturity.
When: Though Collards tolerate hot weather, the leaves taste better in cool weather and it is as a winter crop that it really comes into its own. If you only gather a couple of leaves from a plant each time, it will continue to grow strongly.
How: Take leaves from the bottom of the plants and leave the growing heart alone.

Culinary Use:
Collards dark green edible leaves can be prepared by sauteing or steaming. They often are served with smoked meats. Collards and black-eyes peas are a traditional New Year's Day dish. Collards are also great when prepared with bacon.
Leaves: raw or cooked. A strong cabbage flavor, they are delicious if used when fairly young though they can become tough with age. The leaves are usually available from autumn to late spring, and can be harvested all through the winter in all but the very coldest of seasons.
Young flowering shoots: raw or cooked. Picked before the flowers open, they are fairly tender and can be used as part of a mixed salad. When cooked, they have a delicious flavor similar to sprouting broccoli.
Companion Planting
Companions: companion gardeners sometimes recommend collards for a trap crop around the cabbage patch. However, research indicates that such a practice may only make things worse, increasing rather than decreasing the number of pests on the cabbages.
Enemies: Companion gardening lore warns against planting collards or other cabbage family crops near grapes.

There are beetles that look similar to soldier beetles such as blister beetles and click beetles, so use care when identifying them. Soldier beetles are not commercially available.
Since Soldiers Beetles lay their eggs in the soil, all you have to do to is grow good nectar or pollen producing plants like Asclepias (milkweed), Solidago (goldenrod), and, while it’s not well understood, they seem particularly attracted to hydrangeas. Soldier Beetles can be found on flowers where they lie and wait for prey. They also feed on nectar and pollen but do not damage the plants.

They also eat nectar from flowers. The adult is recognized by the long legs and tapered abdomen but also by the metalic green or blue color. Larvae of long-legged flies are maggot-like in appearance and develop in wet or dry soil, rotting vegetation, or under bark. They are not commercially available.
Syrphid, Flower, or Hover Flies: Syrphid flies are about the size of house flies and hover in flight. The adults, which sometimes resemble bees, are not predaceous, but the larvae are aphid predators. The larvae vary in color from green to brown, some with a stripe or two down the back. The body tapers to the mouthparts. Syrphid flies are not commercially available.

Collard greens are an extremely rich source of vitamin K and also contain folate, thiamin, niacin, pantothenic acid, choline, phosphorus and potassium.
Bone health: Low intakes of vitamin K have been associated with a higher risk for bone fracture. Adequate vitamin K consumption is important for good health, as it acts as a modifier of bone matrix proteins, improves calcium absorption and may reduce urinary excretion of calcium.
One cup of boiled collard greens provides a whopping 770 micrograms of vitamin K; well over 100% of the daily-recommended need.
Cancer: Since the 1980s, maintaining a high intake of cruciferous vegetables has consistently been associated with a lower risk of developing colorectal and lung cancer. Recently, cruciferous vegetable intake has been linked with targeting prostate cancer cells as well. These vegetables have sulfur-containing compounds known as glucosinolates, which have been studied for their ability to impede the cancer process at different stages of development for lung, colorectal, breast, and prostate cancers. New preliminary studies have found that glucosinolates may also be effective against melanoma, esophageal cancer, and pancreatic cancer.
Collard greens and other green vegetables that contain high amounts of chlorophyll have been shown to be effective at blocking the carcinogenic effects of heterocyclic amines, which are generated when grilling foods at a high temperature. If you tend to like your grilled foods charred, make sure to pair them with green vegetables to help negate these effects.
Diabetes: Studies have shown that type 1 diabetics who consume high-fiber diets have lower blood glucose levels and type 2 diabetics may have improved blood sugar, lipids and insulin levels. One cup of boiled collard greens provides about 8 grams of fiber.
The Dietary Guidelines for Americans recommends 21-25 g/day for women and 30-38 g/day for men.
Collard greens also contain an antioxidant known as alpha-lipoic acid, which has been shown to lower glucose levels, increase insulin sensitivity and prevent oxidative stress-induced changes in patients with diabetes. Studies on alpha-lipoic acid have also shown decreases in peripheral neuropathy and/or autonomic neuropathy in diabetics.
Of note, most studies have used intravenous alpha-lipoic acid and it is unsure whether oral supplementation would elicit the same benefits.
Digestion: Collard greens are high in both fiber and water content, which help to prevent constipation, promote regularity and maintain a healthy digestive tract.
Healthy skin and hair: Collard greens are also great for your skin because they are packed full of vitamin A, a nutrient required for sebum production that keeps hair moisturized. Vitamin A is also necessary for the growth of all bodily tissues, including skin and hair.
Adequate intake of vitamin C (one cup of boiled collard greens provides over 50% of daily needs) is needed for the building and maintenance of collagen, which provides structure to skin and hair.
Iron-deficiency is a common cause of hair loss, which can be prevented by an adequate intake of iron-containing foods like collard greens. Not getting enough iron in your diet can also effect how efficiently your body uses energy. Collard greens are a great non-heme source of iron, along with spinach, lentils, tuna and eggs.
Sleep and mood: The choline in collard greens is an important nutrient that helps with sleep, muscle movement, learning and memory. Choline also helps to maintain the structure of cellular membranes, aids in the transmission of nerve impulses, assists in the absorption of fat and reduces chronic inflammation. Folate, also found in choline, may help with depression by preventing an excess of homocysteine from forming in the body, which can prevent blood and other nutrients from reaching the brain. Excess homocysteine interferes with the production of the feel-good hormones serotonin, dopamine, and norepinephrine, which regulate not only mood, but also sleep and appetite as well.

American colonists later brought them to the New World, where they became a commonly enjoyed food both for their roots and their greens. According to historians, George Washington experimented with beets, cross-pollinating them to create new varieties.

Milkweed: Showy (Asclepias speciosa)
Milkweed: Swamp (Asclepias incarnata)
As the name indicates, these swamp milkweed seeds for sale thrive in swamps and low meadows or along streams. The bright pink flowers attract swarms of bees and butterflies, and have a sweet scent described as similar to vanilla or cinnamon. At one time, the silk from swamp milkweed seed pods was spun for fabric or used for stuffing pillows; in World War II, school children gathered the silk to provide a cheap filling for soldiers' life jackets. Commercial attempts to make use of this abundant plant included the manufacture of paper, fabric, lubricant, fuel, and rubber; eventually these became impractical and were abandoned. Though this plant is toxic to most animals, butterflies are immune to the plant's poison and actually become rather poisonous themselves as protection from predators.
